WebWith only the sides given, you'd have to solve for an angle using the law of cosines. If the triangle had a right angle, you could use the inverse trig functions. The law of cosines is: c^2 = a^2 + b^2 - 2*a*c*cos (C) a, b, and c are sides of a triangle, and C is the angle included between a and b.
